Subject: Samba Config Help - Permissions?
I am replacing an old system running RH9 with a new one running CentOS5, this system is a fileserver only. On the old RH9 system I had it configured so that one Samba user had no password, this user has read only access to the server and is the Windows user on my Mame arcade system (no keyboard so it's impossible to have a password on that system). I can not figure out how to get it configured the same way on my new CentOS5 system. I created the user, deleted the user's password, added the user to the Samba Users list, and still no go. Can someone please provide a bit of assistance on this??? I'd like to add to this and also post the smb.conf as requested. I was just testing further and found that a user, apape, has read access to some shares (data, and mp3) yet not write access, and this user does not have any access to another share (rosanne). The user apape is in the following groups: apape, rmusel, root. Also the user apape has no access to their own home directory. To further add to this, the user rmusel has read access to data and mp3 as they should. This user has no access to rosanne nor their own home directory. Clearly something is off on my permissions, I just do not know what. I have the same share settings as I did in the RH9 system and everything there worked perfectly. Here's what is in my smb.conf file. # This is the main Samba configuration file. You should read the # smb.conf(5) manual page in order to understand the options listed # here. Samba has a huge number of configurable options (perhaps too # many!) most of which are not shown in this example # # For a step to step guide on installing, configuring and using samba, # read the Samba-HOWTO-Collection. This may be obtained from: # http://www.samba.org/samba/docs/Samba-HOWTO-Collection.pdf # # Many working examples of smb.conf files can be found in the # Samba-Guide which is generated daily and can be downloaded from: # http://www.samba.org/samba/docs/Samba-Guide.pdf # # Any line which starts with a ; (semi-colon) or a # (hash) # is a comment and is ignored. In this example we will use a # # for commentry and a ; for parts of the config file that you # may wish to enable # # NOTE: Whenever you modify this file you should run the command "testparm" # to check that you have not made any basic syntactic errors. # #--------------- # SELINUX NOTES: # # If you want to use the useradd/groupadd family of binaries please run: # setsebool -P samba_domain_controller on # # If you want to share home directories via samba please run: # setsebool -P samba_enable_home_dirs on # # If you create a new directory you want to share you should mark it as # "samba-share_t" so that selinux will let you write into it. # Make sure not to do that on system directories as they may already have # been marked with othe SELinux labels. # # Use ls -ldZ /path to see which context a directory has # # Set labels only on directories you created! # To set a label use the following: chcon -t samba_share_t /path # # If you need to share a system created directory you can use one of the # following (read-only/read-write): # setsebool -P samba_export_all_ro on # or # setsebool -P samba_export_all_rw on # # If you want to run scripts (preexec/root prexec/print command/...) please # put them into the /var/lib/samba/scripts directory so that smbd will be # allowed to run them. # Make sure you COPY them and not MOVE them so that the right SELinux context # is applied, to check all is ok use restorecon -R -v /var/lib/samba/scripts # #-------------- # #======================= Global Settings ===================================== [global] # ----------------------- Netwrok Related Options ------------------------- # # workgroup = NT-Domain-Name or Workgroup-Name, eg: MIDEARTH # # server string is the equivalent of the NT Description field # # netbios name can be used to specify a server name not tied to the hostname # # Interfaces lets you configure Samba to use multiple interfaces # If you have multiple network interfaces then you can list the ones # you want to listen on (never omit localhost) # # Hosts Allow/Hosts Deny lets you restrict who can connect, and you can # specifiy it as a per share option as well # workgroup = apape.net server string = Samba Server Version %v netbios name = Warehouse ; interfaces = lo eth0 192.168.12.2/24 192.168.13.2/24 ; hosts allow = 127. 192.168.12. 192.168.13. hosts allow = 192.168.12. 127. # --------------------------- Logging Options ----------------------------- # # Log File let you specify where to put logs and how to split them up. # # Max Log Size let you specify the max size log files should reach # logs split per machine log file = /var/log/samba/%m.log # max 50KB per log file, then rotate max log size = 50 # ----------------------- Standalone Server Options ------------------------ # # Scurity can be set to user, share(deprecated) or server(deprecated) # # Backend to store user information in.

strange that you smb.conf is so large. mine is : [global] # workgroup = NT-Domain-Name or Workgroup-Name, eg: LINUX2 workgroup = WORKGROUP netbios name = eServer # server string is the equivalent of the NT Description field server string = eServer Music Share # Security mode. Defines in which mode Samba will operate. Possible # values are share, user, server, domain and ads. Most people will want # user level security. See the HOWTO Collection for details. security = share [public] comment = Music Share path = /mnt/terra/Music browseable = yes guest ok = yes public = yes read only = yes The only other thing i can think of is you access control list, you have : hosts allow = 192.168.12. 127. Might need to be : hosts allow = 192.168.12.0/24 127.0.0.1
